D EVICE FOR FlLLlNG RECEPTACLLESl SPECIFICATION formingpart of Letters Patent No. 633,913, dated September 26, 1899. Application filed January 17, 1899, Serial No. 702,467. (No model.)

To all wiz/0111, it 11i/ay concern:

Be it'known that I, ALFRED P. SILVER- THORN, a citizen of the United States, residing at Ridley Park, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in De`V `"ices for Filling Receptacles; and I do declare the following to be a full, clear, and exact def scription of the invention, such as will enable improvements in devices for filling receptacles, and especially toan apparatus of this nature in which a double tube or two-way passage is provided in a spigot, one tube or passage-way being provided through which the liquid is designed to flow, while the other pas-V sage-way serves as a vent to allow air to replace the space from which .liquid is drawn..-

The present invent-ionrelates, further, to a filling device whereby an opaque receptacle may be 'filled or partially filled at differentv heights and the supply automatically out olf` when the receptacle is illedqto the neckof the filling-aperture or partially filled, as may be desired, means being provided to prevent gurgling in the supply-reservoir and the passage of bubblesinto the receptaclebeing filled.V

To these ends and to such others as 'the invention may pertain the same consists, fur;l ther, in the novel construction, combination, and adaptation of the parts, as will be here# inafter more fully described and then spe-A ing a spigot having two ,passage-ways, said spigot being shown as applied to a stationary reservoir andone of the passage-ways being somewhat longer than the other and upwardly bent. Fig.V 3 is a sectional view of a cock which may be employed in said spigot.

Reference now being had to the details of the drawings by letter, A designates thereservoir, which may be small and portable, in which case the-filling device may be held in the neck of the reservoir, and when the spigot is used it is preferably to be applied to a sta tionary reservoir, as a barrel or can.

The filling-tube B is made with a longitudinal partition, making two passage-ways through the tube or spigot, one of said pasvsage -Ways being somewhat smaller, the smaller duct or passage-way being indicated by letter D, which serves as a vent, and the.

`larger one by letter E, through which latter the liquid is designed to flow. 'Theportion of the tubing outside of the reservoir carrying sameis downwardly bent and adapted to ,be inserted in the filling-apertu re of a reeep.

tacle which is to receive the liquid from the reservoir. The inner end of the filling-tube on its under side is cut away, as at El', mak- 'ing the passage-way through which the liquid is designed to pass Vsomewhat shorter than the vvent passage-way,this shorteningof the liquid passage-waybeing for the purpose of preventing bubbles passing out with the liquid when ,the surface'of the liquid in the receptacle being filled comes up adjacent to the end of the vent which is inserted in the receptacle. By this provision the liquid will flow into the receptacle in a solid unbroken stream until the liquid ceases to flow.

Y When the spigot is used, preferably on larger reservoirs than in the construction Ashown in Fig. 1, it is my purpose to have theV ,innerl end D of the veut passage-way up; wardly bent, so as to separate farther the openings at the inner ends of the spigot. At auysuitable location in the spigot is the two- .way valve H, whereby the low of oil and air through the passage-ways may be prevented. y In operation the end of the filling-tube is inserted in the receptacle to be filled or partially filled and the end of said tube held at such a height inY the receptacle at which it is desired to lill' the latter and the liquid is allowed to flow into the receptacle until the surface of the liquid rises up to the openings in the outer end of the tube, when the vent passage-way will be closed, not allowing any more air to enter the reservoir to replace the liquid, and the flow will cease. In order to prevent bubbles entering into the receptacle,

IOO

the inner end ol the vent-tube beingnpwardly bent or extending farther in the res ervoil' than the under passage-way will separate the openings such a distance as to allow the liquid to flow in an unbroken stream until the receptacle is iilled to the desired' height.

By inserting the end of the tube or spigot. into the filling-aperture of the receptacle, Which may be done in ease the receptacle is a fount for a lamp, while the lamp is burning the gases in the fount may be conducted away from the fonnt to the reservoir, thus avoiding possible explosions.

lVhen my filling-tube is applied to a portable receptacle or reservoir, as a can, it may be securely fastened to a cap or a cork, as shown, and the shape 0E the tube or spigot and passage-ways therein may be varied with- ALFRED P. SILVERTHORN.
